ELECTRIC TROLLEYE SPECIFICATION forming part of Letters Patent No. 777,616, dated December 13, 1904.

Application filed April 13, 1904.

To all whom it may concern.-

Be it known that I, THEOPHILE EUPHRAT, a citizen of the United States of America, and a resident of Norwalk, county of Fairlield, and

5 State of Connecticut, have invented certain new and useful Improvements in Electric Trolleys, of which the following is a specification.

My invention relates to trolleys for overhead conducting-wires; and it consists of the improved ice and sleet detaching attachment hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is a side elevation of a trolley and part of the pole with my attachment applied. Fig. 2 is a plan view of the same.

A represents the upper part of the pole, and b the wheel of an ordinary electric trolley.

c is an ice and sleet detaching wheel of an at- 2 'tachment which Iapply for temporary use in times when the wire is coated therewith in a manner enabling it to be readily brought into and out of action, as occasion requires, it being undesirable to run the ice-detaching wheel on the wire continuously on account of the injurious effect of the wire on the ice cutting and breaking ribs with which the wheel is provided and of the injurious elfects of said ribs on the wires.

The wheel 0 is mounted in bearings carried by an arm or arms (Z, mounted on the pivot e of the wheel Z), so as to swing into position for taking the wire Z from said wheel, so as to detach the ice and to swing out of such position and allow the wire to return to its nor mal position on wheel 6 again when the occa sion for its use has passed. Various contrivances of means may be employed for so operating said wheel 0, and while I have represented herein what I consider the preferable means at the present time I do not limit myself in this respect. The said means consists in this example of the branch arms f, preferably extending downward from the hub of arms (Z, with a coiled tension-spring g connected to the free ends and also connected to the pole A or to the lower end portion of the Wheel-bearing fork it under suitable tension Serial No, 202,896. (No model.)

to hold when not restrained the ice-cutting wheel up into action, with a cord 7? attached to any suitable part of said bearing for wheelc to pull and tie said wheel out of action when not required for usefor example, to tie it to the pole below fork it.

A reinforcing flat or other compression spring 7' may be employed for maintaining the action of the wheel 0 on the wire and for a stay against lateral vibration. Provision will of course be made for transi'nission of current through wheel 0, same as in the other wheel.

What I claim as my invention is 1. In an electric trolley, the combination. with the conducting-wire, pole, and the usual trolley-wheel carried on said pole, of an icedetaching conducting-wheel, means for maintaining it normally out of action relatively to the conducting-wire, and means for actively engaging it with the wire, and at the same time disengaging the usual conducting-w heel.

2. In an electric trolley, the combination with the conducting-wire, pole, and the usual trolley-wheel carried on said pole, of an icedetaching conductingavheel, bearings for said Wheel carried on the pivot of the said usual wheel and adapted for normally maintaining it in disconnected relation to the wire, and means for shifting it into connection and maintaining it in substitution for said usual wheel with the wire.

3. In an electric trolley, the combination with the conducting-wire, pole, and the usual trolley-wheel carried on said pole, of an icedetaching eond noting-wheel, bearings for said wheel carried on the pivot of the said usual wheel and adapted for being normally secured in a position for maintaining it in disconnected relation to the wire, and a spring for shiftii'lg it into connection with the wire and maintaining it in substitution for said usual wheel with the wire.
